Spiral cleaning machine for small potatoes

Abstract

The invention relates to a spiral cleaning machine for small potatoes. The spiral cleaning machine comprises a frame, a spiral cleaning cage, friction wheels, sleeves, a transmission mechanism, a motor and an anti-deformation device. The spiral cleaning cage is positioned on the frame, and a feeding funnel is arranged at the inlet end of the spiral cleaning cage. The spiral cleaning cage body is acylindrical cage body formed by a spiral line, the sleeves are correspondingly arranged at the two ends of the spiral cleaning cage body, each sleeve is in rolling contact with a friction wheel corresponding to the sleeve and is driven to rotate by the friction wheel, and the friction wheels are driven to operate by the motor through the transmission mechanism. The anti-deformation device is arranged in the spiral cleaning cage, a main shaft of the anti-deformation device is coaxially arranged with the spiral cleaning cage, three anti-deformation rods are uniformly distributed on the inner wall of the spiral cleaning cage, the main shaft is connected with the three anti-deformation rods through multiple groups of support columns, and the main shaft is connected with vertical frames through bearings. Material guide plates are correspondingly arranged at the portions, connected with the corresponding anti-deformation rods, of the groups of support columns. The spiral cleaning machine makes full use of the gravity of the potatoes and the soil, so that the soil and the potatoes can be more fully separated.

Description

Technical field: [0001] The invention relates to an agricultural harvesting and cleaning machine, in particular to a small potato spiral cleaning machine. Background technique: [0002] In 2015, my country launched the strategy of turning potatoes into a staple food. Potatoes can be processed into staple foods such as steamed bread, noodles, and rice noodles. Potatoes will become another staple food besides rice, wheat, and corn. Affected by this, the potato planting area has expanded year by year in recent years, and the national planting area has exceeded 85 million mu; the planting area has increased, and the number of small-sized potatoes lost is increasing. When potatoes are mechanically harvested and sorted, small potatoes (D≤ 35mm) has reached more than 90%. Some data show that under normal circumstances, the small-sized potatoes missed account for 5% of the total potato production. Only some areas of small potatoes are harvested manually, which requires a lot of manp...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of small potato spiral cleaning machine, this small potato spiral cleaning machine is used to solve the problem that small potatoes are harvested manually, which requires a lot of manpower, financial resources, time and the low efficiency of manual picking of small potatoes in the northern region. As a result, most of the small-sized potatoes were not harvested in time, causing huge economic losses, so as to solve the shortcomings of the current potato field sorting line
